What this means

jsonata: Malicious inputs to "$toMillis" function can cause resource exhaustion affects jsonata (npm). Severity is high. ### Impact In JSONata `<v2.2.0`, it is possible to craft non-matching inputs to the [$toMillis](https://docs.jsonata.org/date-time-functions#tomillis) function that cause superlinear backtracking in the ISO-8601 validation regex. This may lead to denial of service in applications that evaluate user-provided JSONata expressions. ### Patches This issue has been addressed in JSONata version >= 2.2.0 via fixes that include https://github.com/jsonata-js/jsonata/pull/782 and https://github.com/jsonata-js/jsonata/pull/793. Applications that evaluate user-provided expressions should update ASAP to prevent exploitation. ### References https://github.com/jsonata-js/jsonata/releases/tag/v2.2.0 ### Credit Thank you to Doruk Tan Öztürk for disclosing this issue.

AI coding agents often install or upgrade packages automatically in npm. A high vulnerability in a dependency can be pulled into a project through a normal install or update without a human reviewing the change, expanding the blast radius from a single package to every agent workspace that depends on it.
